Back to Basics: How Do I Pick My Foundation?

Earlier this week, I was in Denver and my skin was PARCHED from the high altitude. The result? My foundation looked totally crappy--and it got me thinking that my foundation never looks that good, and that it's probably time to buy a new base. (Plus, after checking out Julianne Hough's skin while writing The Ultimate Guide to Gym Hair, I really knew it was time because her skin is so freaking perfect.) While I always go to a pro to help choose the right shade (Hint: go at least two hours after a workout and make sure you're skin is bare to get the best match), finding the perfect formula can be a MAJOR pain, no matter who is (or isn't) helping you. The good news? I'm making the whole process a lot easier for you.
